JavaScript to Python- a few differences in syntax

When you are learning a new programming language it can be hard to keep the syntax straight in-between the two languages. Here is a quick reference of some basic differences between JavaScript and Python.

Naming Conventions-

• JavaScript uses lowerCamelCase as a naming convention.

• Python uses the snake_case as a naming convention.
  

// JavaScript
aNewCupOfCoffee

# Python
a_new_cup_of_coffee

Declaring variables-

• JavaScript uses const, let, and var to declare variables.
• To declare a variable in Python, it is set to the value- variable = value.

// Variable in JavaScript
const kaiBear = "super fluffy pupper"

# Variable in Python
kai_bear = "super fluffy pupper"

Creating Functions-

• In JavaScript we create functions by using the function keyword and surrounding the function body in curly braces.

• To create a function in Python use the def keyword and add a colon after the parentheses.
  

// JavaScript function
function newRamenMenu(){
   // write code here
}
# Python function
def new_ramen_menu():
    # write code here

Code Blocks-

• JavaScript uses curly braces to group statements together.
• To create a code block in Python you indent (press the space bar 4 times) continuous lines of code.

// A code block in JavaScript
if (a > 3){
  console.log(a);
}

# A code block in Python
if a > 3:
    print(a)

Creating Comments-
Single line comments

• Single line comments are written in JavaScript with two slashes(//).

• Python writes single line comments with a hashtag, or the pound sign (#)
  

// This is a comment in JavaScript

# This is a comment in Python

Multi-line comments

• Multi-line comments are written in JavaScript by starting with a /* and ending with */.

• Python writes multi-line comments with a hashtag, or the pound sign (#) at the beginning of each line.
  

/*
This is a multi-line 
comment in JavaScript.
*/

#This is a multi-line
#comment in JavaScript.
